f To all whom .it may concern Be it known that I, OSEPH G. SMITH, of Philadelphia, Pennsylvania, have in ventedan Improved Rectifying Apparatus, of which the followingis a specication:

The object of my invention is aV saving of time and the economy of ltering material in' the recti-fying of spirits. This object I attain in the manner which I'Will now'proceed to describe, reference being had to the accompanying drawing, in which-,y

Figure l isa vertical section of the rectify# ing apparatus, and Fig. 2 a sectional plan on the line l i y The outer cylindrical casing A of 'therectt fying apparatus is surmounted by a removable cover, a, through `the center of whichV 4passes a pipe, B, communicating with an elevated reservoir containingthe crude spirit, or with a pump, and terminatingin a central chamber, b, from Which radiate a number of perforated tubes, d, closed at their outer end, so that the spirit will pass, in a number ot' small streams, over the entire surface of a perforated plate, f, Which rests on a mass of charcoal, D, supportedon a diaphragm, h, -Which rests on ledges or bracketsin the interior of the casing. The'spirit, after percolating through this mass of' charcoal, must pass through -the perforated walls of a central chamber, E, on the abovementioned diaphragm h, and thence into aseries of radial tubes similar to those above referred to, and in small Widely-disseminated streamsfrom these tubes onto a mass, H, of charcoal, supported by a partially-perforated diaphragm, i', which also rests on a ledge or bracket in 4 the casing. 'The perforated-portion of this diaphragm is limited to the central portion of the same, extending from a: to fz, the remaining or outer annular portion ot' the dia-Y phragm heilig closed, so that the spirit, in percolating through the second mass ot' charcoal, will be directed tothe central perforated portion of the diaphragm, and avoids the lower corner of the mass of charcoal, Where it might otherwise be lodged and retainedv longer than desirable.v Y

The spirit, passing through the perforations of the diaphragm i, falls onto a third mass of charcoal, G, supported by a perforated diaphragin,'1n,an outer annular portion of the latter heilig also free from perforations, for thereasons mentioned above.

The spirit passes through the perforations of the diaphragm m into the lowest chamber I of the casing, and thence, through a perfo'- rated or Wire-gauze plate a, into the dischargepipe p, which it leaves in the desired rectified condition'.

i Around the edge of each of the diaphragms 1 I h, z', and m may be placed a layer, z, of plasterof-paris or other equivalent material, Which will prevent the passage of any ofthe liquor around the said edges, and thereby prevent the escape from the apparatus of any liquor which has not' been thoroughly rectified.

It should be understood that the highest mass of granulated charcoal is comparatively coarse, the nextbelow somewhat finer, andV l. The within-described spirit-rectifying ap- Y paratus, consisting of a casing inclosing successive and entirely separated layers of gran,-

ulated filtering material of various degrees ofr tineness,and with open spaces between each layer, in combination with means, substantially as described, for spreading the liquid into minute streams.

2. rlhe combination, in a casing, A, of the supply-pipe B and its stationary radial perforated arms With the perforated plate f and the underlying mass D of charcoal. I

3. The centrally-perforated. diaphragm i,

having an imperforate annulus supporting thev mass H of charcoal Within thecasing A, in

combination with the lower centrally-perforated diaphragm, having an i'mperforate` annnlus supporting` another layer ofeharcoal above the outlet-chamber, as specified..

4. The combination of the imperfrat'e diaphragm h, having a central opening, the diaphragm i, havin gan mperforate annulus,wth f the diaphragm m, having a narrower' mp'erfoi rate annulus, making complete separate chambensi-within. the; casing A,-.substantial1y as and foritheipnrposes; herein set forth.

In testimony whereof I have signed my name to this specilcation in the presence of two sub- JOSEPH C.y SMITH.
